2. Open armor (circumcision). For jujube trees that grow vigorously, cut the phloem by opening the armour, so that the nutrients produced by the leaves are concentrated for flowering and fruit setting. Open armor is suitable for trees with a diameter of 10-15 cm or more. The optimal period for opening a carapace is the blooming period. The specific method is: gird the main stem 10-20 cm from the ground, with a width of 0.3-0.5 cm, reaching the xylem. After peeling, wrap the wound with a plastic film. 3. Reasonable control. Before flowering (from late April to early May), 0.5-0.75 kg of urea should be applied to each tree, 0.25 kg of urea should be applied to the first-fruiting tree, and nitrogen and phosphorus should be applied again after flowering (mid-to-late June). , Potassium compound fertilizer, 0.75 kg per plant. Spraying 10-50% gibberellin solution in the early blooming period or spraying 0.3% borax solution in the blooming period can significantly increase the fruit setting rate. 4. Irrigate before flowering and spray water during flowering. If the soil is too dry before flowering, it should be irrigated in time to ensure stable fruit setting. Spraying water every 2 to 3 days during the full blooming period of jujube trees can promote pollination and fertilization and increase the fruit setting rate. 5. Put bees in the jujube garden. Jujube flowers are typical insect-pollinated flowers, and placing bees during the flowering period can increase the fruit-setting rate. Generally, 1 box of bees is placed for every 6 acres to 10 acres of jujube garden. Disclaimer: Some articles on this website are transferred from the Internet.

Five Tips to Promote Jujube Trees
1. Pruning, topping. The first pruning is done when sprouting in spring, and summer pruning is done at the full and final flowering period. Erase the useless shoots from the trunk and the backbone branches and other branches that consume the nutrients of the tree. When the newly born jujube grows to 25 to 30 cm, the core should be topped to control the growth of developing branches, increase the growth of secondary branches, and promote fruit setting.
